Here's a first whack, proof-of-concept on how we could start to
decouple the platform_device from an omap_device.

The main RFC is in the last patch, and everything leading up to it are
misc. omap_device cleanups that make the last patch cleaner and
clearer.  It's really the last patch that does the decoupling.

This will be necessary if we're going to decouple the platform_device
creation from the omap_device/omap_hwmod creation etc.  This patch
leaves them both done in omap_device_build(), but shows that they can
be decoupled.
Can you pls mention baseline used for these patches? I tried applying on
latest mainline, v3.0 and  git://git.pwsan.com/linux-2.6 prcm-devel-3.1
Oops, sorry.  I forgot to mention it.

Due to some misc. dependencies (mainly on Beagle board file), I've
temporarily based it on the for-next branch of the arm-soc tree[1]
since that has everything already queued for the next merge window. I
also based it on the omap_device patch I posted which changes the pr_*
prints to dev_*.

For convenience, I've pushed this series to the 'wip/od-devres' branch
of my tree[2].

Sorry for the confusion,

Kevin

This series results in boot crash. However, it boots fine without this series. 
I have not tried to debug but it looks like from boot log, the res structure has
invalid entries in mmc probe. As mentioned by Grant in 7/7, the scope of devres 
is not lifetime hence it needs to be fixed.
